The push button start system has become a staple in modern vehicles, offering a convenient and sleek way to start your car. However, what happens when this system fails, and you’re left stranded? Can you manually start a push button start car? In this article, we’ll delve into the world of push button start systems, explore the reasons why they might fail, and discuss the possibilities of manual starting.
Understanding Push Button Start Systems
Push button start systems, also known as keyless ignition or start/stop systems, use a combination of sensors, computers, and actuators to start the vehicle. The system typically consists of:
- A key fob with a transponder chip that communicates with the vehicle’s computer
- A push button or switch that sends an electrical signal to the computer
- A starter motor that turns the engine over
- A battery that provides power to the system
When you press the push button, the computer checks for the presence of the key fob and verifies the authentication code. If everything checks out, the computer sends an electrical signal to the starter motor, which turns the engine over.
Why Push Button Start Systems Fail
While push button start systems are convenient, they can be prone to failure. Some common reasons why these systems fail include:
